Description

The DAC8560 is a low-power, voltage output, 16-bit digital-to-analog converter (DAC). The DAC8560 includes a 2.5-V, 2-ppm/°C internal reference (enabled by default), giving a full-scale output voltage range of 0 V to 2.5 V. The internal reference has an initial accuracy of 0.02% and can source up to 20 mA at the VREF pin. The device is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages (glitch). The DAC8560 uses a versatile 3-wire serial interface that operates at clock rates up to 30 MHz. It is compatible with standard SPI, QSPI, Microwire, and digital-signal-processor (DSP) interfaces.

The DAC8560 incorporates a power-on-reset (POR) circuit that ensures the DAC output powers up at zero scale and remains there until a valid code is written to the device. The DAC8560 contains a power-down feature, accessed over the serial interface, that reduces the current consumption of the device to 1.2 µA at 5 V.

The low-power consumption, internal reference, and small footprint make this device ideal for portable, battery-operated equipment. The power consumption is 2.6 mW at 5 V, reducing to 6 µW in power-down mode.
